A Cleveland police officer shot 12-year-old Tamir Rice about two seconds after the officer and a partner pulled up in a car to investigate reports that someone was brandishing a gun at a park , surveillance video that police released Wednesday shows .

Tamir , who had what police said is an air gun that looked like a real firearm , died Sunday , a day after he was shot outside a recreation center .

Police also released two audio recordings Wednesday -- a 911 call preceding the shooting and a tape of a dispatcher asking officers to go to the park .

The shooting happened after a person called 911 to report that a black male -- `` probably a juvenile '' -- was pointing `` a pistol '' at people outside the recreation center . Twice the caller said the gun might be fake .

The dispatcher radioed to officers about a black male who was `` pointing a gun at people , '' but did not mention that caller 's belief that he could be a minor and that the gun might not be a real firearm , one of the released recordings shows .

Police previously said it was n't clear if the responding officers received the information about the suspect 's age or the gun possibly being fake .

Authorities are investigating the shooting , and the two officers -- identified Wednesday by police as Timothy Loehmann , 26 , and Frank Garmback , 46 -- are on leave from their jobs .

Loehmann joined the department in March , Tomba said .

Deputy Police Chief Ed Tomba stressed that his department released the video at the request of Tamir 's relatives , who had seen it privately with authorities ' permission .

`` We are honoring the wishes of the family , '' Tomba said . '' ... This is an obvious tragic event . ''

In a written statement obtained by CNN affiliate WEWS , the family thanked the police for making the video public .

`` It is our belief that this situation could have been avoided and that Tamir should still be here with us , '' the family said . `` We ask for the community to remain calm . Please protest peacefully and responsibly . Your prayers , kind words and condolences have meant so much to us .

Video shows officer shoot Tamir

The video shows Tamir walking along a sidewalk and eventually sitting on a picnic table bench under a gazebo Saturday afternoon , sometimes pointing what appears to be a handgun .

Eventually , Tamir emerges from the bench and walks to the edge of the gazebo . A police car drives up to the gazebo , leaving the road and rolling over snowy grass to do so .

One of the officers -- the one in the passenger seat -- told Tamir three times to `` show your hands , '' Tomba told reporters .

'' -LRB- The officer 's -RRB- door was open as they pulled up , '' Tomba said . `` He yelled three times as they pulled up . ''

The eight-minute surveillance video has no audio .

Police have said Tamir reached into his waistband and pulled out the weapon . The video shows Loehmann , the passenger-side officer , exiting the car , and Tamir falls down , apparently shot .

Between 1.5 to two seconds elapsed from the time the car pulled up to the moment Tamir was shot , Tomba said . At that point , only the passenger-side officer was out of the car , the video shows .

One of the officers , radioing to dispatch , reported that a `` black male , maybe 20 , '' was down , according to the released radio traffic between the officers and dispatchers .

The driver was Garmback , a six-year veteran of the force , according to Tomba .

Chief Calvin Williams said that four minutes after Tamir was shot a detective and FBI agent were on the scene . The FBI agent began first aid and paramedics arrived three minutes later .

Investigators determined that Tamir 's weapon was an air gun , and that an orange tip that is meant to indicate that it 's not a real firearm had been removed , police said .
